Removal of Phenol by Ozonation in Strongly Alkaline Conditions using a Jet Loop Reactor Operated in Continuous Phase

open access: yesGlobal Challenges, EarlyView.
This study presents the removal of phenol by ozonation in a continuously operated jet loop reactor (JLR) under strong alkaline conditions. The effects of ozone concentration, hydraulic retention time, and influent phenol levels on phenol, COD, and TOC removal are evaluated to assess the efficiency of JLR‐based ozonation.

Wet‐dry cycles control the emissions and sources of greenhouse gases in agricultural soil: An incubation study

open access: yesJournal of Environmental Quality, EarlyView.
Abstract This study examines the impact of wet‐drying cycles and nitrogen (N) fertilization on soil greenhouse gas fluxes, specifically nitrous oxide (N2O) and carbon dioxide (CO2). Nine treatments were tested, combining three soil moisture regimes (55% constant, 55%–30% cycle, and 80%–55% cycle) with three N addition rates (0, 100, and 150 kg N ha−1 ...

A tephrostratigraphic investigation of the continuously varved Holocene Boreal lake Nautajärvi, Finland, provides precise age estimate for Lairg A/Hekla 5 eruption

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resolved continuous sediment archives. Lake Nautajärvi is located in central‐southern Finland (61°48′ N, 24°41′

Raman Analysis of Roman Mosaics From the Upper Guadalquivir Valley (Spain)

open access: yesJournal of Raman Spectroscopy, EarlyView.
This work is focused on the Raman analysis of two Roman mosaics from Jaén (Spain) using portable and benchtop equipment, complemented by elemental analysis using EDXRF and petrographic analysis. The results obtained have provided a detailed characterisation of the tesserae.
